A network model to simulate performance of variable refrigerant volume refrigeration systems.

Author(s) : SHI W., SHAO S., LI X., et al.

Summary

Variable refrigerant volume (VRV) refrigeration systems have been widely used in residential and light commercial buildings. A fluid network model has been developed to simulate the performance of VRV systems consisting of multiple indoor/outdoor units. This model is based on analysis of system structure, refrigerant flow direction, and refrigerant states in the pipes of a refrigeration system. The characteristics of a heat recovery VRV system with two indoor units were simulated to demonstrate the application of the model. The steady-state performance in different modes and different conditions can be predicted by the model, which would be helpful for analyzing and optimizing a complex refrigeration system under variable operating conditions. This model can serve as an analytical design tool for manufacturers, consulting engineers, research institutions, and universities to improve the performance of multi-unit refrigeration systems such as a VRV system.
